Each LI-COR custom service offers the choice of a dye or quencher from the LI-COR portfolio of IRDye® infrared dyes and VRDye™ visible fluorescence dyes. In addition, LI-COR offers ROS (reactive oxygen species) probes, protocol development, and custom derivation of fluorescent dyes.

"By leveraging our years of experience in near infrared dye conjugation and fluorescence detection, we are able to expand our product offerings to include non-catalog items and projects," says Dr. Peter Johnson, LI-COR senior field application scientist and innovations manager.

LI-COR will provide a Certificate of Analysis (COA) at the request of the customer with every order that may include HPLC purity, Mass Spec and NMR analysis, extinction coefficient, final concentration, free dye determination and dye-to-protein ratio, depending on the requested synthesis or conjugation.
